The meaning of BRYOZOAN is any of a phylum (Bryozoa) of aquatic mostly marine invertebrate animals that reproduce by budding and usually form permanently attached branched or mossy colonies.Bryozoan colony attached to a rock in the Baudette River Each fall the bryozoans begin to die off, but create overwintering "eggs" that will form new colonies the next year. When the colony is dying, gas produced by decomposition may cause it to float loose, sending gelatinous globs floating down the river. The Flora and Fauna Guarantee Act 1988 (the FFG Act) provides for the listing of taxa (genera, species, subspecies and varieties), threatened communities of flora and fauna and potentially threatening processes.

While they are more abundant and common in marine environments, they have also adapted to freshwater habitats.

Moss Animals: Phylum Bryozoa. Bryozoans, sometimes referred to as "moss animals," are a type of simple colonial animal that mostly lives in marine environments (a few inhabit freshwater). Bryozoans feed by means of a lophophore, a small ring of tentacles covered with tiny cilia that are used to filter food from the water.Abstract. The Bryozoa (Phylum Ectoprocta), also known as Polyzoa in some older literature, is a group of small, sessile, colonial, filter-feeding animals. The majority of the members are strictly marine, but there are at least 65 freshwater species worldwide (Wood & Wood, 2000). The phylum is divided into three classes: the Stenolaemata which ...Bryozoans are tiny colonial animals.

Bryozoans are exclusively clonal aquatic animals that can exhibit various growth forms: some branch up from substrate, some grow into amorphous ...Bryozoa is a phylum of usually sedentary colonial marine invertebrates. Colony morphologies are diverse, typically encrusting or branching, many of them calcified. In all species, the majority or totality of the colony is composed of (typically) box- or cylinder-shaped "autozooids," which feed, providing nourishment for the colony.Zooids have a u-shaped crown of 19-24 ciliated, orange translucent tentacles, called a lophohpore, which is extended through its aperture to feed. W. Subtorquata lacks spines, avicularia, and ovicells common to many bryozoans. An identifiable characteristic is its black, sinusoid aperture, having a convex proximal border (Cohen 2005).

The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch.

The colony shapes range from simple encrusting … examples of time sampling Bryozoans are tiny, structurally complex organisms that live in colonies made up of modular, skeletonized living chambers called zooids. These microscopic homes allow their inhabitants to pop out to feed on plankton and then retreat if danger threatens.
